EMBOSSING- APPARATUS.

Speccaton of Letters Patent.

Patented Apr. 6, 1915.

Application led J une 2, 1914. Serial No. 842,370.

Be it known that I, FREDERICK WV. REIN- DEL, a citizen of the United States, and a resident of East Cleveland, county of Guyahoga, and State of Ohio, have invented a new and useful Improvement in Embossing Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements relate in general to book binding apparatus, and more particularly to a device for rapidly and conveniently applying the embossed lines, which are sometimes placed upon the covers of books for ornamental purposes, one such line often running vertically from top to bottom of the book at about the point where the back is oined to the cover.

My improved device is constructed to permit of continuous operation, and means are provided which maintain the embossing material in a semi-plastic condition thus causing the same to be readily and properly applied to the work in hand without sticking to the embossing wheel or roller. The device is also adjustable, adapting it to receive embossing wheels of various widths to operate on dierent work.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings Figure 1 is a view in perspective of my invention sho-wing the same in position to operate upon a book; Fig. 2 is a plan view of the same showing the cover plate removed; Fig. 3 is a sectionon the line 3 3 in Fig. 2; Fig. 4 is a section on the line L1 4, Fig. 2; Fig. 5 is a section on the line 5 -5, Fig. 2; and

Figs. 6 and 7 are diagrammatic views showing modifications.

Referring now to Fig. 1, the device will be seen to comprise a handle 1 which is preferably formed hollow and is provided at its outer end with a projecting shank or plate 2 having a circular oifset disk 3, to which there is removably attached a shallow, preferably cylindrical, casing 4 open at one end. Such casing has an opening in its closed end which is closed by the disk 3 when the casing is mounted thereon. The disk 3 is provided with a threaded opening 5 disposed concentrically with respect to said casing. Within the casing and attached to the closed end of the same is a concentric collar 6 extending to a level with the edge of the open end of the casing. Between the outer wall of the casing 4 and this collar 6 there is packed refractory material 7 in which is embedded a suitable electrical heating coil 8 having connection 4% extending through the hollow shank 2 and through the handle 1 where such connections or wires may terminate in a suitable block (not shown) adapted to be engaged in an electrical socket.

An embossing wheel or roller 9 is provided, which is centrally apertured, and is provided on its under side with a concentric collar 10 fitting loosely into the collar 6 formed in the casing. This collar 10 abuts against a thrust bearing consisting of a projection 11 formed integrally with the disk 3. When the collar 10 on the roller 9 is in operative contact with the projection 11 in the casing 4 the roller 9 is substantially in contact with the refractory material 7 in the casing, and is thus heated thereby when the electrical coil 8 is energized. The roller 9 is maintained in such position by means of a screw 12 provided with an enlarged portion 13 rotatably mounted in the aperture in the collar 10 on the roller and threaded be yond such point to removably engage in the threaded aperture 5 in the casing. This embossing roller is formed peripherally in the usual manner with a series of suitable designs adapted to transfer the embossing material, such for example as gold leaf, tothe work.

Mounted upon the shank 2 adjacent to the casing are two spaced plates 15 andv16,

upon the upper of which 16, is mounted a rotatable stud 17 adapted to receive a spool 18 upon which there is wound'embossing ribbon 19, such ribbon consisting of a narrow strip of very thin paper upon the inner side of which there is lightly attached thin gold leaf.

Mounted in the same plane as the emboss# ing roller and upon the upper plate 16 is a feed roller 20. Such feed roller is rotatably mounted upon a pin 21 attached to a slide,

of the embossing roller,`this action `causingthe ribbon to be drawn between the two rollers, when thegold leaf will stickto the periphery of the embossing roller as will be readily understood'. The feed `roller is preferably provided peripherally with a friction face 25 of some suitable material.

The' paper Vstrip of the ribbon 19 from which theleaf or other embossing material has been removed is passed around the feed roller 20 between the latter and Va smaller roller 26 which maybe termed a discharge roller, which is mounted similarly to the feed roller upon a pin 27 projecting upwardly from a slide 28 mounted beneath theV slot formed in the upper plate Abetween such plate and the lower one. A second spring 29 is provided for maintaining this discharge roller in operative position with respect to the feed roller. Operation of theembossing roller 9 thus draws the'ribbon 19 between the same and the feed roller 20 and causes the stripped ribbon toA be discharged from between, the feed and discharge rollers against a guideway 30 which causes the same .to pass out of the casing. A latch 45 or othermeans may be provided tofhold the roller 20`out of engagement with the roller 9, such latch engaging behind the pin 21'.

The embossing roller will beoperated in the direction of the arrow in Figs. land 2, and will contact'the work at the line indicated. Between such point of contact with the work where the leaf isremoved from the :surface of the embossing .roller and applied to the work and the pointat which the embossing material is neXt Aapplied to the roller, there are mounted means adaptedA to render the surface of the roller moreV adhesive to the embossing material than is the ribbon thus causing the gold to be transthe ribbon will stick tothe periphery of the roller, it will not adhere thereto whenthe oily surface of the roller. The spring 33 is adapted to maintain the cup 31 in either operative or inoperative position as may be desired, such spring bearing against either of two flatsides on the cup as best shown ming. 2.

A third plate 34 is provided for the purpose of covering Ythe various rollers mounted upon the second plate, 16, such plate 34 being provided'with open slots 35 removably'enjgaging' in coperative slots 36 formed in the sides of-'two pins 37fmounted at the two extremities of the plate. When the plate has been engaged with these two pins a slot 38 formed in the plate'` registers with the two pins 21 and 27Vupon.which are mounted the feed and discharge rollers, Vthus maintaining Vthe latter in position but permitting the same to-move as has already been described. A central aperture is formed in this cover plate adapted to receive a central screw 4l mounted on the second plate 16 and about -such screw there is mounted a coiled spring 42 adapted to maintain the plate 34 away from the second plate. A knurled nut 43 Ais provided for adjusting the cover plate longitudinally of this screw against the tension ofthe spring. Y Y

It will be understood that embossing rollers of various thicknesses may be used Vupon the same casing, it being only necessary to remove the screw 12 which engages the end of the casing when the embossing rollermay be lifted outY and a different one inserted. In. order toproperly' apply the embossing material tothe surface ofsuch'new roller it is desirable to remove the feed roller and the spool and Ysubstitute a feed rol/lei' of a different thickness'to wcorrespond toY the increased thickness ,of the embossing roller and similarly a spool of widerV ribbon will beY mounted upon the rotatable stud. Although not *absolutely essential in such circumstances, it is desirable to also provide a discharge roller of corresponding thickness, and this may be doneif desired. The cover plate is then positioned with its slots; en-

"roller contacts the work by reasonV of the Y loo gaging the coperativel slots formed in the upper ends of the twopins when the plate may be tightened against the.rollersfby the ribbon in which the embossing material is on the outside of the paper. Under such conditions the spool 18 may be positioned upon the pin 21 on the slide 22, and will thus directly contact the periphery of the embossing roller 9, the waste ribbon being then led around the spool between the latter and the discharge roller. The operation of the device under these conditions will be readily understood, and it will be seen that the principle of operation is the same as when the feed roller is used to draw the ribbon between such roller and the embossing roller.

The appearance of the device when the spool 18 is mounted directly against the embossing roller is shown in Fig. 6, while in Fig. 7 I illustrate a roller 51 having a notch 52 adapted to receive the end of the strippedl ribbon, which is then wound upon the roller 5l, which may be displaced in the slot 24 to compensate for the increasing diameter.

My improved embossing tool possesses numerous advantages over the device now in general use for this purpose, in which merely a roller is provided which is first supplied with embossing material by being given a complete revolution when pressed against a supply of the material. This prevents the tool from forming continuously a line of greater length than the circumference of said roller. rlhe present tool can be used continuously, since it is always supplied with embossing material by its own operation in the manner already described.

Other important features which coperate to secure the results obtained with this device are the lubricating means and the means for heating the embossing roller. By making it possible to conveniently and quickly remove the various rollers the tool is given a wide range of use since other sets of roller of varying widths may be substituted, adapting the device to perform a number of kinds of work.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1.
